Read the following passag: As the process of digestion in the stomach nears completion, the contraction of the stomach decrease. This prompts the muscles called as pyloric shincter opening of the stomach and the first part of the small intestine or duodenum to realax. This opens the pathway into duodenum releasing the partially digested food (chyme) in small quantities into the duodenum. Peristalsis involves the contractin of the muscle behind the food and the relaxation of he muscles in front of the food and the relaxation of the muscles in front of the food giving rise to na thrust that pushes the food forward through the digestive canal. A wave of contraction followed by realaxtion in muscles help in forward movement of food. Wirte answer for the following questions. What is the use of peristalsis movement ?
